WebMar 4, 2024 · Figure 4: My beagle, Janie, undergoes Canny and Holistically-Nested Edge Detection (HED) with OpenCV and deep learning. There are two objects in this image: (1) Janie, the dog, and (2) the chair behind her. The Canny edge detector (center) does a reasonable job highlighting the outline of the chair but isn’t able to properly capture the … WebAug 9, 2024 · Canny edge detection algorithm produces smoother, thinner, and cleaner images than Sobel and Prewitt filters. Here is a summary of the canny edge detection algorithm-. The input image is smoothened, Sobel filter is applied to detect the edges of the image. Then we apply non-max suppression where the local maximum pixels in the …
